Dynamic migration of user interface application

ABSTRACT

Primary tables associated with a first user interface application are received in a migration of user interface application layer. Properties associated with the primary tables and secondary tables are determined. The primary tables and the secondary tables are converted to an entity data model file in a migration system based on the properties associated with the primary tables and the secondary tables. A service and a link to access the service are generated based on the entity data model file. UI controls corresponding to the properties determined from the service are identified in the migration system. A second user interface application with the UI controls is displayed in the enterprise application.

DETAILED DESCRIPTION

Embodiments of techniques for dynamic migration of user interface application are described herein. In the following description, numerous specific details are set forth to provide a thorough understanding of the embodiments. One skilled in the relevant art will recognize, however, that the embodiments can be practiced without one or more of the specific details, or with other methods, components, materials, etc. In other instances, well-known structures, materials, or operations are not shown or described in detail.

Reference throughout this specification to “one embodiment”, “this embodiment” and similar phrases, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one of the one or more embodiments. Thus, the appearances of these phrases in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

Various enterprise applications such as enterprise resource planning (ERP) applications, customer relationship management (CRM) applications, content management applications, business intelligence applications, database management applications, etc., are developed and used in organizations. The enterprise applications have various functionalities, and provide users with appropriate user interfaces to interact with the enterprise applications. The user interface (UI) application layer of the existing enterprise applications can be migrated to a different or new UI application layer. FIG. 1 is a block diagram illustrating an exemplary environment 100 for dynamic migration of user interface application layer, according to one embodiment. ‘Enterprise system A’ 102 is shown executing ‘enterprise application A’ 104 as a multi-tier or multi-layer application with ‘UI (user interface) application layer A’ 106, ‘application layer A’ 108, ‘database layer A’ 110, ‘layer N’ 112, etc. The ‘enterprise system A’ 102 may be a specialized enterprise system with hardware components such as high speed processors, physical memory, hard drives, network connections, etc., capable of hosting and executing specialized enterprise software applications such as ‘enterprise application A’ 104. The ‘migration application A’ 114 enables migration of ‘UI application layer A’ 106 in the ‘enterprise application A’ 104 to ‘UI application layer B’ 116. ‘Migration system A’ 118 is shown executing ‘migration application A’ 114 that enables and ensures seamless migration of ‘UI application layer A’ 106 to ‘UI application layer B’ 116 with minimal or no downtime while execution of ‘enterprise application A’ 104. The ‘migration system A’ 118 may be a specialized enterprise hardware system with hardware components such as high speed processors, physical memory, hard drives, network connections, etc., capable of hosting and executing specialized enterprise software applications such as ‘migration application A’ 114.

FIG. 2 is block diagram 200 illustrating components in a migration application, according to one embodiment. ‘Migration application’ 202 executing in a ‘migration system’ has various components such as ‘entity data model (EDM) generator’ 204, ‘XML engine’ 206, ‘service generator’ 208, ‘UI generator’ 210, ‘in-memory view generator’ 212, log generator′ 214, ‘generator APIs’ 216 and ‘control tables’ 218. Generators may be software implementations with application logic along with hardware implementations to enable and support execution of the application logic. ‘EDM generator’ 204 receives primary tables and related tables such as secondary tables as input, and generates entity data model (EDM) file based on metadata. ‘Metadata parser’ 220 parses metadata of data in the received tables. ‘Metadata XML converter’ 222 converts the parsed metadata to an EDM file format. ‘Read XML’ 224 in the ‘XML engine’ 206 may read the EDM file, and ‘parse XML’ 226 may parse the EDM file, and enables the EDM file to be sent to ‘in-memory view generator’ 212. ‘XML engine’ 206 may also parse and enable EDM file to be sent to ‘service generator’ 208. ‘Service generator’ 208 reads the EDM file and generates services. ‘Link generator’ 228 in the ‘service generator’ 208 generates links to access the generated services. ‘UI generator’ 210 reads the input from the generated services and generates a UI screen based on a style sheet provided as input to the ‘UI generator’ 210. Individual processes in the ‘migration application’ 202 are logged in the log generator′ 214. ‘Generator APIs’ 216 serves as a communication mechanism between the different generators and the ‘control tables’ 218. ‘Control tables’ 218 such as ‘EDM generator control table’ 230, ‘in-memory view control table’ 232, ‘service generator control table’ 234 and ‘UI generator control table’ 236 are generated for the individual generators, and data corresponding to the generators are stored in the respective control tables.

FIG. 3 is block diagram 300 illustrating user interface of migration application, according to one embodiment. Migration application provides various functionalities such as generate entity data model (EDM) 302, generate in-memory views 304, generate services 306, and generate UI screens 308. In an enterprise application to migrate existing UI screens to different UI screen, tables from the enterprise applications are selected. For example, a table named ‘employee’ 310 is selected and ‘get relations’ 312 is clicked. Other tables such as ‘address’ table 314 and ‘assignment’ table 316 related to the ‘employee’ table 310 are retrieved and displayed as shown in table 318. ‘Employee’ table 310 and ‘address’ table 314 may have a 1:N association between them. ‘Employee’ table 310 may have properties or fields such as employee_ID, employee_name, employee_ob, employee_gender, etc. ‘Address’ table 314 may have properties or fields such as address_ID, address_line, city state, country, etc. Data type and the length of the properties or fields are also specified for both ‘employee’ table 310 and ‘address’ table 314. User may manually add additional tables using ‘add’ button 320 and may remove the previously added tables using ‘delete’ button 322. When a user clicks on ‘generate’ button 324, ‘employee’ table 310 and the related tables ‘address’ table 314 and ‘assignment’ table 316 are converted to an EDM file. The EDM file may be in the form of an XML file.

FIG. 4 is flow diagram 400 illustrating EDM generator, according to one embodiment. At 402, it is determined whether a primary table is provided as input. Upon determining that the primary table is not provided as input, at 404, an error message is logged in a log file and the process is terminated. Upon determining that the primary table is provided as input, at 406, a primary key is obtained for the primary table using a function. At 408, it is determined whether the primary key is used as a foreign key. Upon determining that the primary key is used as the foreign key, at 410, secondary tables associated with the foreign key are obtained. At 412, a list is generated including secondary tables along with relationships or associations between the secondary tables and the primary table. At 414, properties of the primary table and the secondary tables in the list are determined. At 416, based on the properties, using XML engine, the primary table and the secondary tables are converted to an EDM file. At 418, the converted EDM file is stored in an EDM generator control table. EDM file format may be in an XML file format.

FIG. 5 illustrates an exemplary EDM file, according to one embodiment. ‘Employee_EDM’ file 500 generated by an EDM generator is shown containing data associated with primary table named ‘employee’ table and secondary tables named ‘address’ table and ‘assignment’ table along with user defined tags in the form of an XML file. Data associated with individual properties or fields of ‘employee’ table, ‘address’ table and the ‘assignment’ table are specified in the EDM file 500. For example, for the ‘employee’ table a property EmployeeID is specified as <Property Name=“EmployeeID” Type=“Edm.String” Nullable=“false” sap.label=“Emp ID”/> in the EDM file 500. Similarly other properties such as name, date of birth and gender are indicated. Similarly, in ‘address’ table various properties such as addressID, employeeID, address, city and country are specified in the EDM file 500. Association tag is used to specify association between ‘employee’ table and ‘address’ table by indicating multiplicity of associations. Multiplicity may be many-to-many, one-to-many, etc., between the tables in the association.

FIG. 6 is flow diagram 600 illustrating service generator, according to one embodiment. An EDM file is provided as input to the service generator in a user interface of a migration application. At 602, the EDM file named ‘employee_EDM’ file is read and provided as input to the service generator. At 604, the ‘employee_EDM’ file is parsed to check for presence of errors. Upon determining presence of errors, at 606, the errors are logged in a log file and the process is terminated. Upon determining that there are no errors in the ‘employee_EDM’ file, at 608, services and links to access the services are generated. Service ‘employee_service’ and a link ‘http://abc.xyz.com/employee_service_url’ to access the service ‘employee_service’ are generated. At 610, links to access the generated services are stored in a service generator control table. At 612, the services are registered in a server for user access.

FIG. 7 is flow diagram 700 illustrating in-memory view generator, according to one embodiment. At 702, determine whether an EDM file is provided as input. Upon determining that the EDM file is not provided as input, at 704, an error message is logged in a log file and the process is terminated. Upon determining that the EDM file is provided as input, at 706, the EDM file is parsed to check for presence of errors. Upon determining that the EDM file contains errors, at 708, an error message is logged in the log file and the process is terminated. At 710, properties, types of properties, association between the primary and secondary tables, type of the association, multiplicity are identified from the EDM file. At 712, in-memory views are generated based on the types of properties and the type of association. At 714, the in-memory views are executed. At 716, it is determined whether the in-memory views are successfully executed. Upon determining that the in-memory views are successfully executed, at 718, the in-memory views are stored in an in-memory view generator control table. Upon determining that the views are not successfully executed, at 720, the errors are logged in the log file.

FIG. 8 is flow chart 800 illustrating UI generator, according to one embodiment. Service ‘employee_service’ generated as output from a service generator is provided as input to a UI generator. UI generator has a dictionary instance where a mapping between a type of a property and a corresponding UI control is maintained. For example, for a property ‘employeeID’ of type ‘edm.string’, a corresponding UI control ‘text box’ is maintained in the dictionary instance. The appearance of the UI control in a user interface is based on a style sheet selected. Appearance such as size, shape, etc., of the UI control ‘text box’ is based on the selected style sheet. At 802, a style sheet is selected for generating a UI screen. At 804, the service is parsed to read data from the service. Service ‘employee_service’ is parsed to read data from the ‘employee_service’. At 806, it is determined whether the service contains properties with single instance of values or multiple instances of values. Values corresponding to properties associated with a single employee may be referred to as a single instance of values. Values corresponding to properties associated with multiple employees may be referred to as multiple instances of values. Upon determining that the service contains properties with single instance of values, at 808, properties with single instance of values are read from the service ‘employee_service’. At 810, corresponding types of the properties with single instance of values are identified. At 812, for individual property types corresponding UI controls are retrieved from the dictionary instance. At 814, the UI controls are added to a UI layout for display. Upon determining that the service contains multiple instances of values, at 816, a table object to hold the properties of multiple instances of values is initialized. ‘Employee_service’ contains multiple instances of values corresponding to properties such as employeeID, name, date of birth and gender.

At 818, the properties of multiple instances of values are read. At 820, types of the properties of the multiple instances of values are identified. Types of the properties employeeID, name, date of birth and gender of the multiple instances of values are identified as ‘edm_numeric, ‘edm_string’, ‘edm_string’, ‘edm_date’ and edm_string′ respectively. At 822, based on the types of the properties corresponding UI controls are retrieved from the dictionary instance. Based on the types of the properties ‘edm_numeric, ‘edm_string’, ‘edm_date’ and edm_string′, corresponding UI controls ‘textbox’, ‘textbox’, ‘datebox’ and ‘textbox’ are retrieved from the dictionary instance. At 824, for the individual types of the properties corresponding columns are added to the table object. For types of properties ‘edm_numeric’, ‘edm_string’, ‘edm_date’ and edm_string′ corresponding columns ‘ID’, ‘Name’, ‘Date of birth’ and ‘gender’ are added to the table object. At 826, details area corresponding to properties associated with the secondary tables is added to the table object. Details area to display address and assignment associated with an employee may be added to the table object. At 828, the table object is added to the UI layout for display. At 830, the UI layout is displayed with the table object as shown in FIG. 9.

Properties such as ID 902, name 904, date of birth 906 and gender 908 are displayed in the UI layout with corresponding values. Additional UI controls such as new 910 may also be added to the UI layout and displayed.

FIG. 10 is flow chart 1000 illustrating migration of user interface application layer, according to one embodiment. At 1002, primary tables associated with a first user interface application are received. At 1004, properties associated with the primary tables and secondary tables are determined. At 1006, the primary tables and the secondary tables are converted to an entity data model file in a migration system based on the properties associated with the primary tables and the secondary tables. At 1008, a service and a link to access the service are generated based on the entity data model file. At 1010, UI controls corresponding to the properties determined from the service is identified in the migration system. At 1012, a second user interface application with the UI controls is displayed in the enterprise application.

Migration application may be available as an installer or executable file packaged and shipped to users along with enterprise applications, or, as a standalone installer or executable file provided to the users. When the users install the migration application, they will be provided with a user interface wizard as shown in FIG. 3.

Some embodiments may include the above-described methods being written as one or more software components. These components, and the functionality associated with each, may be used by client, server, distributed, or peer computer systems.
